Plasma renin activity in hypertensive and hypotensive turkeys.

Plasma renin activity (PRA) and Angiotensin I values were determined in hypertensive and hypotensive strains of turkeys. In this study, PRA and/or Angiotensin I values were not influenced by body weight or blood pressure. The PRA of the hypertensive turkeys (.227 ng/ml/hr) was not significantly different from the hypotensive turkeys (.216 ng/ml/hr). Also, the Angiotensin I values of .225 and .213 ng/ml in the hypertensive and hypotensive lines, respectively, were not different. There were no significant correlations between body weight, blood pressure, PRA, and/or Angiotensin I.
